PKES is based on Radio Frequency Identification(RFID) technology for authentication of the authorized drivers. RFID technology has replaced the conventional ways of identification and authorization in order to facilitate users while introducing new security challenges. In this article, we focused on verifying the presence of authorized key in the physical proximity of car by employing multiple antennas. Application of multiple antennas to the currently developed cryptographic algorithms opens a new approach for researchers to improve security of RFID based systems. We propose an advanced security system for PKES using multiple antennas wherein an authorized key passes through multiple vicinities to allow driver to access and start the car. Furthermore, we modified a light-weight cryptographic protocol named as HB(Hopper and Blum) protocol to integrate it with the proposed design based on multiple antennas. Simulation results show improvement in security functionality while keeping in view the efficiency constraints.展开更多
文摘针对基于智能手机的汽车无钥匙进入和启动系统(PEPS)车内外高精度辨识技术需求,设计基于双终端的差分K近邻定位算法.通过改进的Dempster-Shafer证据理论,将双终端算法与典型单终端算法的辨识结果进行融合,提升识别算法的鲁棒性与准确性.与传统的K近邻和概率分布法相比,融合算法在实验场景中对终端车内外状态的辨识准确率提升10%.在传统定位算法易出现误判的车窗附近范围内,将误差距离从距车窗20 cm缩小到距车窗5 cm.
